Copper extraction Wikipedia

Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales and the dense metal particles do not react with froth flotation media Typically if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings

Flotation Reagents Mineral Processing Metallurgy

Flotation Frothers What is the Function of Frothers The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non floatable minerals Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form
